>>13757434Except if a set contains an element then it is not empty, and emptiness, or null, is therefore not contained in the set. Another way to put it: Is emptiness contained in what is filled? Or, is there empty space (void) in a plenum?
By allowing the empty set be a subset of a non-empty set you are essentially appending the empty or null element in the set. E.g. Inherently, A = {1}, B = {_}, B is a subset of A, so A = {1, _ }
stupid fuck
